Jamin wants to paint a wall in his bedroom. in order to know how much paint to buy, he first needs to know the approximate area. there is a window in the middle of the wall, so he'll only need to paint the shaded part shown. how many square feet is just the window? [note: the wall and window are both rectangular.]

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
